Step 1: Prepare the Flange and Its Base

Before installing any fixture into an area, it is vital to scout out any obstacles on the way. Such as walls or flooring that may need to be removed in order for installation teams to access plumbing lines, all of which will require careful planning. Once these issues have been addressed along with any necessary adjustments made beforehand; one can finally commence constructing their dream bathroom!

Take a look at your flooring and determine whether you’d like to bore a hole or not. If the latter is the case, then the task can be accomplished without creating any damage. After carefully measuring the dimensions of your drain and choosing the appropriate size of bit from our toolbox, get cracking!

Step 2: Remove the Toilet and Its Base

At this point, it’s time to proceed with removing the old toilet. You may wish to employ an apprentice in order to support you during this step of the process. However, if not then one or two people should suffice for its removal.

Unlock your bathroom door, and gather your tools: a hammer and chisel are necessary for shattering the casing along its length.

Step 3: Mount the Toilet Tank to the Toilet Flange

With everything in place, it’s time to affix the tank assembly to the toilet base. This is achieved by hooking up the bolts that secure it to the flange – ensuring they are securely fastened before affixing the nuts on top.

Despite its sturdy stability, do not overtighten the bolts or else you may risk cracking the porcelain; this would lead to a costly repair job.

Step 4: Adjust the Flange

At last, the elongated flange and its cage are securely in place! Gently press downwards upon it, ensuring that it rests snugly within those cavities; for ultimate security, allow an extra half-inch of space between the baseboard and wall.

Once you’ve adjusted the installation hardware, simply fill any leftover spaces with wood scraps or hardware to reinforce it. Then let’s get on with assembling our commode!

Gently grasp the toilet bowl rim and rotate it onto the stem. If necessary, utilize a wrench (or pliers) to assist with this process.

Step 5: Check for Leaks and Mount the Toilet Seat

When it comes to installing a toilet, two important steps are checking for leaks and mounting the toilet seat. Before proceeding with the installation, it is crucial to inspect the area for any potential leaks. This can be done by placing a few drops of food coloring into the toilet tank and waiting to see if the color seeps into the bowl. If there is a leak, it is important to address it before continuing with the installation process. Once the area is confirmed to be leak-free, the next step is mounting the toilet seat. This involves carefully aligning the seat with the toilet bowl and securing it in place using the provided hardware. It is essential to follow the manufacturer’s instructions and ensure a tight fit to prevent any wobbling or shifting of the seat. By thoroughly checking for leaks and properly mounting the toilet seat, you can ensure a successful and trouble-free installation.

Step 6: Seal the Toilet Flange and Install the remainder of the Toilet

Gather 1/2″ of new glue, and then apply it to the flange where the toilet will sit. Allow it to dry thoroughly before proceeding with assembly, if your adhesive is not yet ready-to-use then apply a generous amount liberally along with a thin layer of wax paper placed between the two surfaces until all is set.

Be sure to use screws that are identical in length to those used for your existing toilets.

Ensure the underside of your newly installed commode is level and plumb! If needed, you can employ mortise jacks for extra assurance. Otherwise revamp with mallet strikes followed by sturdy clamps to ensure any misalignment does not occur, this step is essential!

Step 7: Replace Old Fluid Valves with New Ones

The final step in this installation process is sealing your newly installed toilet and replacing the old, corroded ones with new ones.

As an essential part of any project, it’s essential to complete this stage of the job with diligence. If you rush through it or skimp on the job-site supplies such as sealant or plumbing tape, you may find yourself regretting the decision later!

To complete this step entails removing the old valve from its cavity, then carefully wrapping thread sealant around each prong before reattaching them and tightening them up with a wrench. Finally, flipping over the valve cap for added security against leakage potential.


Installing a toilet can be a daunting task, regardless of whether you’re installing a new one or upgrading an existing one. However, with the proper guidance and materials at hand, it’s possible to tackle even the most challenging installations!
